yes it is very different. Its supposed to have bigger volume, and inside if you look in the stock airbox, it has a hole bunch of fins(they are restrictive). The whisper doesnt have those. About the baffle-it is the big box kind of looking thing behind your airbox. That is the air silencer, when removed it gives more performance, and slightly better sound of your engine/exhaust.
